This paper proposes a CDC restoration scheme for multi-domain optical networks with three or more domains.
Although a CDC restoration scheme for two-domain networks has been previously proposed, directly extending the scheme to three or more domains inevitably requires the propagation of inter-domain connection point information between non-adjacent domains, which may compromise the confidentiality of sensitive network information. To overcome this issue, we propose a CDC restoration scheme that relies solely on adjacent-domain information and evaluate its effectiveness.
